Coast Guard Officials say four boaters left from Clearwater pass on a fishing trip early Saturday morning in a 21-foot boat.
NFL Officials have confirmed that Oakland Raiders Linebacker Marquis Cooper and Detroit Lions Defensive End Corey Smith are among the missing boaters.
The coast guard is searching a 750-square mile area by sea and air.
Authorities say the current weather conditions are making the search difficult.
Coast guard searchers are encountering 14-foot seas and 30 mile-per-hour wind gusts, that make it hard to spot the small white boat.
