Carolina Panthers tight end Mike Seidman has a torn anterior cruciate ligament in his right knee and will likely miss the rest of the season.
Seidman, who had been starting, injured his knee in the win over Tampa Bay on Sept. 24, but coach John Fox claimed they didn't know it was a torn ACL until ``the last couple of days.''
Seidman is not yet on injured reserve.
``There are different options and we're sorting those out,'' Fox said Wednesday.
Kris Mangum and Michael Gaines are expected to split time at tight end.
Meanwhile, linebacker Dan Morgan will miss his fourth straight game since suffering at least the fifth concussion of his career in the opener against Atlanta. On Monday, Fox said Morgan was not considering retirement.
Centre Justin Hartwig returned to practice and listed as questionable for Sunday's game against Cleveland. Hartwig has missed the past three games after suffering a pulled groin against Atlanta.
