Colorado Rapids has exercised the option on midfielder Tony Cascio, who spent the 2014 season on loan to Houston Dynamo. The transaction which took Cascio from Colorado to Houston was the first intraleague loan in MLS history.

The 24-year-old was originally acquired by the Rapids out of the 2012 MLS SuperDraft. In his first two seasons with the Rapids, he made 42 appearances (22 starts). A highlight for Cascio was his last-gasp goal at Montreal Impact during the 2013 campaign. The Rapids won 4-3, snapping a three-game losing streak and starting a nine-game run without defeat.

He featured in five of the Dynamo's opening seven games, starting four of them, before reporting discomfort in his right knee at the end of April and being sent for an MRI scan. The results showed that Cascio had torn the ACL (anterior cruciate ligament) and he only returned as a substitute for the final 15 minutes of the Dynamo's last game of the season, on October 24, having been sidelined for six months.
