The Minnesota Vikings had concerns about Teddy Bridgewater's knee following a postseason medical evaluation.

Mike Zimmer was asked at the NFL owners meetings about his perspective on the health of the quarterback and what he witnessed after Bridgewater returned to practice this past November.

"The reports I'd get back from the medical people weren't as positive as I was about it," Zimmer said. "That's kind of how it came down is that his knee wasn't as ... he still has some recovery to do. When I watched him in practice, he moved well, I didn't see limitations, but, from what I was told, there was some."

The Vikings allowed Bridgewater to walk in free agency and he signed with the New York Jets.

Bridgewater dislocated his knee during a noncontact drill on Aug. 30, 2016.

Andrew Luck has begun throwing footballs again, according to new Indianapolis Colts coach Frank Reich.

The news is a notable step in the offseason process after Luck missed all last year with his shoulder injury.

Luck hasn't played in a football game since Jan. 1, 2017.

Howie Roseman says Carson Wentz is ahead of schedule in his rehabilitation from a torn ACL.

Wentz tore the ACL and LCL in his left knee in December against the Los Angeles Rams. Recovery time for such an injury is typically nine to 12 months, but Wentz has set Week 1 as his target for a return.

Wentz recently posted a video on social media of himself throwing inside the Philadelphia Eagles' practice facility.
