Here are Tuesday’s minor signings, cuts, and other non-trade transactions from around the NFL:

• The Saints signed wide receiver T.J. Graham while cutting fullback Austin Johnson and safety Akeem Davis, according to Evan Woodbery of The Times-Picayune (Twitter links)

Earlier Updates:

• The Chargers, once again dealing with a banged-up offensive line, are re-signing veteran center J.D. Walton, per Adam Caplan of ESPN.com (Twitter link). Chris Watt, who had seen some time at center, was among San Diego’s offensive linemen who left Sunday’s game against the Ravens due to an injury.
• With Keenan Allen headed to the injured reserve list, the Chargers will also be signing wide receiver Javontee Herndon, who had been on the club’s practice squad, per Michael Gehlken of the San Diego Union-Tribune (Twitter link). Herndon certainly won’t be counted on to emulate Allen’s production, but he’ll provide some depth for San Diego’s receiving corps.
• The Texans are signing former Chiefs sixth-round pick Eric Kush to their 53-man roster, a source tells Aaron Wilson of the Houston Chronicle (Twitter link). The 26-year-old interior offensive lineman will join the Houston roster in the wake of a knee injury to C/G Greg Mancz, Wilson observes (via Twitter).
• Former Jaguars linebacker James-Michael Johnson is signing with the Lions, tweets Ian Rapoport of NFL.com. While Johnson didn’t see much action for either the Jags or Bucs this season, he earned 18 starts for the Browns and Chiefs from 2012 to 2014.

• Removed: DL Kaleb Ramsey (suspended four games for violating the NFL’s policy on performance-enhancing substances)

Tampa Bay Buccaneers

• Cut: LB Julian Stanford (press release via team)

The Buccaneers have placed defensive tackle Clinton McDonald on their injured reserve list, ending his season, the team announced today in a press release. McDonald suffered a pectoral injury last month, and won’t be able to play through it.

McDonald, who joined the Buccaneers prior to the 2014 season, has started 19 games for the team since then, recording 46 tackles and five sacks last year. In just six games this year, the 28-year-old had racked up 31 tackles for Tampa Bay.

The Buccaneers now have an opening on their 53-man roster which figures to be filled within the next 24 hours. As Greg Auman of the Tampa Bay Times observes (via Twitter), that open spot could be taken by tackle Demar Dotson, who is eligible to come off IR-DTR this week.

3:41pm: The 49ers have officially signed Thomas, moving Bush to the season-ending injured reserve list, the team announced today in a press release.

10:00am: A day after signing Shaun Draughn, the 49ers are adding another running back to their banged-up backfield. According to Aaron Wilson of the National Football Post (via Twitter), the 49ers are signing veteran free agent Pierre Thomas. Matt Maiocco of CSNBayArea.com had reported earlier today that Thomas was returning to San Francisco for another visit.

Thomas, 30, saw his 2014 campaign with the Saints derailed by injuries and by an increasing workload for Mark Ingram, who received many of the carries that would have gone to Thomas in past years. Before he finished the season on injured reserve, Thomas ran for 222 yards on 45 attempts, both career-low totals. He did remain fairly involved in the passing game, however, grabbing 45 balls out of the backfield.

Thomas reportedly had a strong workout for the Texans back in August, and later auditioned for the Chiefs in the wake of Jamaal Charles‘ injury, but couldn’t find a deal with either Houston or Kansas City. The Niners hosted Thomas for a tryout a little over two weeks ago, and will now add him to a roster that has been hit hard by injuries.

With Carlos Hyde dealing with a stress fracture in his foot, Reggie Bush and rookie Mike Davis were called upon to carry the rushing load for the Niners in Week 8. However, Bush suffered a season-ending knee injury, and Davis sustained a fractured hand, leaving Kendall Gaskins as the only healthy back on the roster.

San Francisco signed Draughn yesterday to complement Gaskins, and figure to use incorporate the veteran Thomas into the mix as well, at least until Hyde and Davis are healthy enough to return.

The Chargers have announced a series of moves, the most notable of which was previously reported, with wide receiver Keenan Allen landing on the injured reserve list. Another key offensive contributor, running back Branden Oliver, will also head to IR, according to a team release.

Here’s the club’s full list of roster moves:

Signed:

• CB Greg Ducre (from practice squad)
• WR Javontee Herndon (from practice squad; previously reported)
• C J.D. Walton (previously reported)

Placed on injured reserve:

• WR Keenan Allen (previously reported)
• RB Branden Oliver
• OLB Tourek Williams
