CLEVELAND, Ohio -- Browns right tackle Mitchell Schwartz has drawn interest on the first day of the free agency negotiating period from the Bucs, Giants, Vikings and Falcons.

The Browns can still re-sign him even before he officially hits the market Wednesday at 4 p.m.

The other teams can't complete a deal with him until Wednesday.

Schwartz stands to become the highest-paid right tackle in the NFL at about $8.5 million a year.

If he leaves, Austin Pasztor will be a candidate to replace him. Claimed by the Browns in September of 2015, he started the final four games of the season at left guard.

The Browns are also in jeopardy of losing three-time Pro Bowl center Alex Mack, who's drawn considerable interest from the Falcons, according to Bleacher Report's Jason Cole.
