Shariff Floyd has knee operation

EDEN PRAIRIE, Minn. -- Minnesota Vikings rookie defensive tackle Sharrif Floyd had a minor procedure done to ease some pain in his left knee, which he hurt in the team's first preseason game on Aug. 9 against Houston.

Vikings coach Leslie Frazier said the first-round draft pick probably won't play in either of the two remaining exhibitions but "shouldn't miss any time" in the regular season.

"I don't think he'll practice until next week," Frazier told reporters on Monday, according to The Star Tribune. "It's nothing major. He shouldn't miss any time, as far as our regular season is concerned. He won't play this week (at San Francisco) and probably not in the Tennessee game (next week)."

Floyd, the 23rd overall pick in this year's draft, suffered the injury in the second quarter against the Texans and underwent an MRI, which revealed no structural damage.

Frazier told reporters that Floyd underwent the procedure to relieve pain in the front of his knee.

The Vikings also released cornerback Jacob Lacey on Monday, a week after his arthroscopic knee surgery.

After three seasons with Indianapolis and one with Detroit, Lacey signed with the Vikings. He had a chance to make the squad with veteran Antoine Winfield no longer on the team. But he was injured early in training camp and didn't play in any preseason games.

Chris Cook and Josh Robinson are the first-team cornerbacks, with Robinson moving inside to the slot position in the nickel defense and rookie Xavier Rhodes entering as the third cornerback.

Lacey was bothered by a thumb injury before he hurt his knee.

"We'll see how he does in his rehab," Frazier said. "In this business you could always end up back here. You never know."
