New Orleans Saints cornerback Patrick Robinson’s season is over.

The Saints (2-0) placed Robinson on year-ending injured reserve after he badly hurt a patella Sunday, coach Sean Payton said Wednesday.

Robinson, New Orleans’ first-round draft pick in 2010, was injured early in the second half of the 16-14 win over the Tampa Bay Buccaneers (0-2) in Week 2.

Bucs receiver Mike Williams blocked Robinson near the sideline on a running play and pushed him backwards. Robinson’s left foot was forward as he lost his balance, and all of his 191 pounds fell on his right foot and knee, which bent under him. He flipped over and immediately clutched at his knee.

The medical staff placed an inflatable cast around Robinson’s leg, and he was carted off the field as he placed his hand over his mouth and wept.

Payton didn’t elaborate much on Robinson’s injury but said it is one from which “he will be able to fully rehab after surgery and recover from 100 percent.”

“It’s a setback and hurts our team as well,” Payton remarked. “He’s a good corner. It forces other players to step up, and we understand that.”

Robinson has seven career interceptions (one of which he returned 99 yards for a touchdown) and more than 140 combined tackles. He had surgery on his right knee in June to clean up what he described as wear and tear.

Meanwhile, Payton confirmed Wednesday that New Orleans re-signed veteran cornerback Chris Carr, who spent training camp with the Saints but was released Aug. 31. Carr has been in the NFL since 2005 and played his first three years in the league under current Saints defensive coordinator Rob Ryan in Oakland.

Carr replaces Robinson on the roster and joins Keenan Lewis, Jabari Greer, Corey White and Rod Sweeting at cornerback.

“It’s unfortunate that (Robinson) had to go down like that and be out for the season; but if I was going to play anywhere this year again, it was going to be here,” Carr told reporters after his first practice back Wednesday. “I didn’t want to go anywhere else and have to learn a new system and be around new guys and get comfortable again.

“I knew if I came back here, it’s a team I’m already invested in. ... I’m just thrilled to be back here.”
