Sept. 20 (UPI) -- Indianapolis Colts starting linebacker Darius Leonard was ruled out for Sunday's game against the Atlanta Falcons, the team announced Friday.
Colts head coach Frank Reich told reporters Leonard won't suit up against the Falcons due to a concussion. He started feeling concussion-like symptoms after Sunday's game against the Tennessee Titans, and has since been placed in the league's concussion protocol, according to the team.
