Winslow's Surgery More Extensive

CLEVELAND (AP) - Kellen Winslow underwent microfracture surgery on his right knee last month, a more extensive procedure than was initially revealed and one that will require a longer recovery.

The Browns' tight end remains on crutches following the January 30th operation to remove scar tissue and repair cartilage. Winslow tied a team record for receptions last season despite being slowed by a bad knee.

The microfracture surgery involves holes being drilled into bone in the knee to promote blood flow and form scar tissue, which replaces any damaged cartilage. Typically, patients need four months of rehab.

Earlier this week, general manager Phil Savage said he expected Winslow to make a full recovery and be back on the field in June or July.
