Dallas Cowboys Gronkowski did not attend the
NFL Scouting Combine, though his brother Rob did. He declared for the
2010 NFL draft and was projected as high as the 4th round, but went undrafted. On April 25, he signed with the
Dallas Cowboys. On September 4, he made the 53 man roster for insurance purposes in case fullback
Deon Anderson's injuries persisted. He made his first career start on September 19, against the
Chicago Bears. His first career touchdown catch came in the same game on a one-yard pass from
Tony Romo. He became the full-time starter at fullback after Anderson was released on September 24. On October 25, in a
Monday Night Football game against the
New York Giants, Gronkowski missed a blitz pickup on
linebacker Michael Boley, as he ran straight to
quarterback Tony Romo and hit him high. Romo got the pass off to
Miles Austin, but he suffered a fractured left clavicle, which ended his season. Gronkowski was active for 14 of the 16 games and started 7 times as a rookie. He was inconsistent as a lead blocker, while posting 5 carries for 17 yards, 7 receptions for 35 yards and one touchdown. He was waived on September 3, 2011.
Indianapolis Colts On September 4, 2011, Gronkowski was claimed off waivers by the
Indianapolis Colts. On October 25, he was placed on the
injured reserve with a pectoral injury.
Denver Broncos On May 23, 2012, Gronkowski was traded to the
Denver Broncos in exchange for
cornerback Cassius Vaughn. He appeared in 14 games as a backup, making one reception for 11 yards and had no rushing attempts. He wasn't re-signed after the season.
San Diego Chargers On April 23, 2013, Gronkowski signed with the
San Diego Chargers as a
free agent. On August 27, he was placed on the
injured reserve list with an ankle injury. On August 31, he was waived with an injury settlement. ==Personal life==
