Clinton Earl Portis (born September 1, 1981) is an American football running back who is currently a free agent. He was drafted by the Denver Broncos in the second round of the 2002 NFL Draft. He played college football at Miami.
Portis has also played for the Washington Redskins.
Portis starred at the University of Miami. He considered going to the University of South Carolina but a fight that he had at Gainesville High School had his scholarship taken away. He became just the second true freshman to start at running back since the 1975 season. Portis set a school freshman record with five 100-yard performances, and led the team with 838 yards and eight touchdowns on 143 carries (5.9 avg.) in 10 games. He also caught four passes for 44 yards (11.0 avg.) and 2 touchdowns. When Portis was still a relative unknown, Lee Corso singled out Portis's performance during a defeat by Florida State for hustling and never giving up, saying "that kid can play for me any time".
Portis' sophomore season was not as successful as he lost his job to James Jackson and rushed for 485 yards and two touchdowns on 77 carries (6.3 avg.) in eight games. He also added 103 yards on five receptions (20.6 avg.).
However, Portis bounced back in 2001 as the Hurricanes won the National Championship and Portis had his best season rushing for 1,200 yards and 10 touchdowns on 220 carries (5.5 avg.). He also added 125 receiving yards. In the Rose Bowl against Nebraska, Portis ran for 104 yards and a touchdown. He also had a long touchdown reception called back on a holding call.
