HENDERSON, Nev. – The 49ers’ medical chart is growing at a steady rate this training camp, and here is a position-by-position look before Thursday’s joint practice at the Las Vegas Raiders:
QUARTERBACK
Kurtis Rourke: Remains on the non-football injury list, due to January ACL surgery.
RUNNING BACK
Isaac Guerendo: Injured his right shoulder on kick-return duties Aug. 2 and is expected out through the preseason. He’s ramped up individual conditioning this week.
Jordan James: Rookie recently had surgery on his right hand to fix a fractured finger, following a knee issue that sidelined him four practices.
Ameer Abdullah: Placed on season-ending Injured Reserve following Saturday’s rib injury.
Kyle Juszczyk: Sustained a cut on his right calf/Achilles on Aug. 2, returned Aug. 7.
WIDE RECEIVER
Brandon Aiyuk: Sounds like he will remain on the Physically Unable To Perform list into the regular season and return for a Week 6 visit to Tampa Bay on Oct. 12.
Jordan Watkins: Sustained a high ankle sprain in the preseason opener and might return in time for the Sept. 7 season opener.
Jacob Cowing: Returned to practice Tuesday after a hamstring injury in warmups the first day sidelined him 12 practices.
Ricky Pearsall: Probable Week 1 starter got activated off the Physically Unable To Perform list just three practices into camp, once his May hamstring injury was cleared for duty.
Equanimeous St. Brown: Signed just before camp, released July 31, re-signed Aug. 5, placed on Injured Reserve on Aug. 8 (foot).
Andy Isabella: He pulled up lame in Aug. 4 punt-return warmups – either an ankle or hamstring issue — and got cut the next day.
OFFENSIVE LINE
Ben Bartch: His bid to start at left guard was delayed by a quadriceps injury. He came off PUP on July 31, started the preseason opener, and he left practice with an apparent injury Aug. 12.
Andre Dillard: Potential swing tackle debuted in practice this week after an ankle injury had him open camp on PUP.
DEFENSIVE END
Nick Bosa: Rested three practices because of unspecified soreness, returned Aug. 7, was off Tuesday.
Mykel Williams: Sustained a hyperextended left knee in the Aug. 7 practice with the Broncos, and could return next week.
Yetur Gross-Matos: The 49ers hoped to spring him off PUP this week but a knee issue is keeping him there until at least next week.
Sam Okuayinonu: Worked on the side Tuesday after a groin injury initially shelved him Aug. 4.
Robert Beal Jr.: Exited Saturday’s preseason opener with a groin injury after splitting a sack with Sebastian Valdez.
Bradlee Anae: Placed on season-ending Injured Reserve on Wednesday.
DEFENSIVE TACKLE
Kevin Givens: A pectoral tear almost two weeks ago figures to keep him out until midseason, so an Injured Reserve designation is upcoming.
Jordan Elliott: A back issue forced him out of practice Aug. 7 and he’s yet to return; both he and Givens opened camp as starters.
Evan Anderson: A knee contusion kept him out a week but he returned this week to practice.
LINEBACKER
Curtis Robinson: Some 10 months after an ACL tear in practice, he got activated Friday off PUP and showed well in Tuesday’s full-team action as a strong-side option.
Chazz Surratt: Was out a few practices for unspecified reasons but returned this week.
CORNERBACK
Renardo Green: Out since July 25 with a hamstring strain, from breaking up a deep pass. His return was expected this week but it’s been delayed.
Upton Stout: Rookie nickel back has been out with calf tightness since practicing against the Broncos.
Deommodore Lenoir: Marquee starter looks fully recovered after missing four practices with hip tightness early in camp.
Tre Brown: Wasn’t seen at Tuesday’s practice for an unknown reason; played with the third string Saturday.
Fabian Moreau: Has missed a week of practice for an unknown reason.
SAFETY
Richie Grant: A knee injury kept has him out since the Broncos practice, after he rotated between the first- and second-strings in camp.
Malik Mustapha: An ACL tear in January’s season finale figures to keep him out until at least midseason, if not much longer.
Ji’Ayir Brown: Soreness from his offseason ankle surgery has kept him from a couple of practices, but he was in Tuesday on the first-string with Marques Sigle after Jason Pinnock exited before full-team drills.
