Mark Sanchez has been spending a lot of time honing his quarterback game on the football field this offseason. And it appears that the Jets stud signal caller has also spent much of his spare time working on his dating game.

After numerous connections to big time celebrities and supermodels, such as Kate Upton, over the past year, Sanchez is now rumored to be dating model and actress Eva Longoria, according to In Touch Magazine.

Longoria and Sanchez were recently spotted shopping together at a Kings Super Market in Bedminster, New Jersey, where Sanchez owns a home. The couple could also be seen eating dinner and sipping some drinks at New York's Hotel Griffou a few nights later, although Longoria apparently tried to hide her identity by wearing a blonde wig to the restaurant.

Longoria has been linked to other athletes in the past, after being married to Spurs guard Tony Parker for more than four years and reportedly dating Lakers guard Matt Barnes in the past few months as well.

Sanchez' relationship with Upton was never confirmed, but the 25-year-old quarterback was spotted spending some late nights at the supermodel's apartment on occasion at the end of the 2011 NFL season.
