Scott Sicko wants to play in the NFL after all.

Sicko, who announced his retirement Saturday night after going undrafted as a University of New Hampshire tight end, has changed his mind. Sicko has reached agreement on a free-agent contract with Dallas, agent J.R. RIckert told FOXSports.com.

"After Scott initially decided not to play football and pursue his graduate studies, the Cowboys as well as other teams continued to pursue him," Rickert wrote in an e-mail to FOXSports.com. "We maintained active dialogue with the Cowboys and they also continued to speak to Scott. After considering all factors, Scott has decided to become a member of the Cowboys. We are very grateful that the Cowboys have given him this opportunity and he is 100 percent committed."

Sicko's initial decision was a surprise since he was considered one of the top college free-agent tight ends available. Sicko had impressed during his Pro Day workout and private predraft sessions with Indianapolis and Jacksonville. Sports Illustrated reported that San Diego, Jacksonville, Kansas City and the New York Jets had expressed interest in signing Sicko as a college free agent.

Sicko, though, told teams he was done playing football and planned to continue his education instead.

"It was tough telling NFL teams I didn't want to be in their camps,'' Sicko told SI.com. "But it was the right thing."

The 6-foot-4, 251-pound Sicko caught 57 passes for 725 yards and nine touchdowns in his senior season. He also posted drill times at his pro day that compared favorably to the top tight ends invited to the NFL Scouting Combine in Indianapolis.

Sicko is likely vying for a spot on Dallas' practice squad because of the team's tight end depth with veterans Jason Witten, Martellus Bennett and John Phillips on the roster.
