Thomas will undergo surgery soon to repair the damage following a serious knee injury a month out from the NFL draft.
Thomas excelled during the Senior Bowl, drawing praise from NFL scouts at his technique and aggressiveness as he finished off blocks and displayed a nasty streak.
Thomas was drawing second-round and third-round grades from draft analysts prior to the injury and was regarded as a rising draft prospect.
Thomas is still expected to do well in the draft, but obviously the timing of the injury will affect his draft stock.
