San Francisco 49ers quarterback Brock Purdy has been waiting for swelling in his right elbow to reduce so he can have the torn ulnar collateral ligament in it repaired.

That procedure was supposed to happen Wednesday in Arlington, Texas. But, after Purdy met with Dr. Keith Meister on Tuesday, the surgery will be delayed further, a source confirmed to ESPN.

Dalvin Cook underwent surgery Tuesday to repair a shoulder injury that the Minnesota Vikings said was "sustained over the past few seasons."

The Vikings called the surgery "successful" and said Cook "is expected to make a full recovery prior to the start of the regular season."

Cook has dealt with chronic shoulder injuries dating back to his time at Florida State. A 2019 injury, which was reported was a "broken shoulder," forced him to miss the final two games of that season. A related injury forced him to miss some time in 2021 as well.

Philadelphia Eagles right tackle Lane Johnson will undergo surgery for a torn adductor later this week, according to sources.

Johnson played through the injury and delayed surgery after suffering the injury on Christmas Eve against the Dallas Cowboys.

Johnson, 32, was selected as a first-team All-Pro for the second time and earned his fourth Pro Bowl selection this year.

He has not allowed a sack since Week 11 of the 2020 season.

Brock Purdy plans to have surgery to repair his torn UCL on Feb. 22nd.

The surgery will allow Purdy to make a full recovery and be ready for the start of training camp. Dr. Keith Meister will perform the surgery in Dallas. 

Purdy became the starting quarterback for the San Francisco 49ers following the injury to Jimmy Garoppolo. Purdy and Trey Lance are expected to compete for the starting quarterback job in camp.

Patrick Mahomes may not be 100% healthy heading into Super Bowl LVII, but the Kansas City Chiefs quarterback says his ankle is "definitely better" than it was leading up to the AFC Championship Game.

Mahomes injured the ankle in Kansas City's divisional round victory over the Jacksonville Jaguars.
