Landon Cassill said Wednesday he is leaving BK Racing to pursue other opportunities in NASCAR.

Cassill joined BK Racing last season when team owner Ron Devine purchased the assets of defunct Red Bull Racing. Cassill ran all 36 races, with an average finish of 27th.

He said the decision to leave so close to the season-opening Daytona 500 was hard, but terms of his 2012 contract have not been fulfilled and Cassill has been unable to come to an agreement with Devine on a 2013 deal.
