CHARLOTTE, N.C. (AP) — Panthers wide receiver Steve Smith said Thursday his injured left knee isn't coming along quite as well as he'd hoped.
Smith practiced for the second straight day on a limited basis, saying, "It didn't feel as great as I thought it'd feel."
He said he "overdid it a little" in practice.
Smith estimates he's "57 percent" healthy, down from 71 percent he mentioned on Wednesday.
As for whether he'll play Sunday against the 49ers in the NFC divisional playoffs, Smith said "I'll have to see" on Friday.
Coach Ron Rivera expressed some concern, saying Smith didn't look as sharp Thursday in practice as he normally does.
"When you watch Steve and watch the way he does things, there's a smoothness to his movements and stuff — and it's not quite there yet," Rivera said.
Smith said the primary issue is his cutting ability while running routes.
"I'll be all right," he said. "I'm going to need some treatment."
At 34, Smith remains an integral part of Carolina's offense.
The franchise's all-time leader in receptions, yards receiving and touchdowns finished the season with 64 catches for 745 yards and four touchdowns. He's also valuable in that he often requires double coverage, thus opening up things for other receivers as well as the team's running backs.
He's also the only wide receiver on the Carolina roster with any significant playoff experience.
In eight postseason games, Smith has 47 receptions for 782 yards receiving and seven touchdowns and has played in a Super Bowl. He's also run for one score and returned a punt for another touchdown in the postseason.
Smith had six catches for 63 yards in Carolina's 10-9 win over the 49ers on Nov. 10 in San Francisco.
