IRVING, Texas (AP) — The Dallas Cowboys have signed tight end Scott Sicko, three days after the New Hampshire player said he was turning down the NFL to go to graduate school.

Sicko signed a free agent contract Tuesday, reversing course on a decision that he wouldn't pursue NFL offers after he wasn't taken in the draft.

The 6-foot-4, 251-pound Sicko caused an Internet stir with his announcement Saturday. Some applauded the 22-year-old's focus on academics, while others blasted him for passing on a rare opportunity.

Sicko tells The Times Union newspaper of Albany, N.Y., he was surprised by all the attention. He says he is "a 22-year-old kid" who wanted to make sure he made the right decision for himself and fiancee.
