"No," coach Mike Pettine said Monday, per ESPN.com. "I don't know when he will throw again, but he is doing his rehab exercises. He is on the training room protocol with it. There is not any real update with Johnny."
After Tuesday's practice, Manziel explained that he's been experiencing elbow tendinitis since his freshman year at Texas A&M. Manziel also said he's reached out to noted surgeon Dr. James Andrews and confirmed he doesn't need surgery.
Other injuries we're tracking as the NFL gears up for Week 4 of the preseason:
- Niners coach Jim Tomsula told reporters that defensive end Darnell Dockett tested negative for a cracked rib, but acknowledged there is some "cartilage thing" going on with the veteran defender, according to CSN Bay Area's Matt Maiocco. Dockett is expected to be available for San Francisco's Week 1 bout with the Minnesota Vikings.
- Panthers defensive end Charles Johnson and rookie wideout Devin Funchess are getting healthy in time for the final preseason game. Johnson injured a muscle in his neck and shoulder in practice Tuesday but should be available to play against Pittsburgh on Thursday. The same goes for Funchess, who felt some tightness in his hamstring earlier this week.
