CHARLOTTE, N.C. (AP) The Carolina Panthers plan to be cautious with center Ryan Kalil after the four-time Pro Bowl selection sprained his left knee in a preseason game Saturday night against the Miami Dolphins.
''He's very valuable to us obviously,'' coach Ron Rivera said. ''We'll be smart. The whole idea being what we want to do once we get to Jacksonville'' in the regular season opener on Sept. 13.
With Kalil out the Panthers moved starting right tackle Mike Remmers to center and rookie Darryl Williams ran with the starters at right tackle.
Kalil is the latest Carolina player to be sidelined with an injury.
Both are out for the season.
Alexander was waived-injured on Monday. If he clears waivers, he'll revert back to the team's injured reserve list on Tuesday.
With Benjamin out of the mix, the Panthers are still deciding between Corey Brown, Jerricho Cotchery, Ted Ginn Jr. and rookie Devin Funchess as their two starting receivers, although Funchess remains out with a hamstring injury. Funchess is expected to return to practice this week, Rivera said.
Brown dropped two passes in the win over the Dolphins, including one in the end zone.
''He's going to make more (catches) than he's going to miss,'' Rivera said.
Defensive end Charles Johnson remains out while battling a calf injury. He has missed the team's last two preseason games.
Cam Newton practiced Monday after it appeared he was a little shaken up a little when he dove for the pylon on a fourth down run against the Dolphins. Newton appeared to be limping some on the sidelines and didn't return to the game since it was his last scheduled play.
The Panthers are expected to decide between second-year player Kony Ealy and Wes Horton to replace Alexander as the starting right defensive end opposite Johnson. Both players have a sack that resulted in a fumble against the Dolphins, but Ealy has been working more with the first team during the preseason.
''This is typical preseason,'' Rivera said. ''You are going to get two or three (injuries) that are a little more serious than you would like them to be. Unfortunately we are at our two right now and that is where we would like to stay.''
