Dressler was pushed out of the lineup on July 14 due to a hamstring injury. A rookie from Boise State, he returned in Week 2 against Hamilton. Teammates said he showed no ill effects despite carrying 75 pounds more than usual on his injured leg. In fact, after missing two games, Dressler was back at it. He had nine catches for 132 yards and a touchdown against Winnipeg on Aug. 4. The next week, he had seven receptions for 123 yards against Edmonton. He ended up with 934 all-purpose yards (633 punt return, 185 receiving) for second in the league behind only Charleston's Jason Collins (947). Dressler started both playoff games for Saskatchewan before being sidelined by an ankle injury. He had three catches for 39 yards and a touchdown in the team's semifinal win over Calgary. In the championship game against Toronto, Dressler had four catches for 67 yards as the Riders lost 23-19 in double overtime. He finished the season with 1,074 all-purpose yards and eight touchdowns. After his successful run with the Riders, Dressler signed with the NFL's Dallas Cowboys on Feb. 10, 2015.
