Dolphins place Moreno on IR with ACL injury

Oct 14, 2014 - 3:13 PM Davie, FL (SportsNetwork.com) - Miami Dolphins running back Knowshon Moreno was placed on injured reserve Tuesday because of an ACL injury.

The free agent acquisition from Denver played just three games in his first season with the Dolphins and totaled 148 yards with a touchdown on 31 carries.

Moreno had an impressive debut with his new team in the season opener against New England, running for 134 yards and a score in Miami's 33-20 victory. He then suffered an elbow injury on his only carry the following week against Buffalo and missed the next two games.

The 26-year-old Georgia product returned for this past Sunday's game against Green Bay, but had just 10 yards on six rushes and had just one carry after halftime in the 27-24 loss.

Moreno had signed a one-year contract with the Dolphins in March after playing his first five seasons with Denver. He was coming off his best year in 2013, rushing for a career-high 1,038 yards with 10 touchdowns while adding 60 receptions for 548 yards with three scores.

The Dolphins also reinstated the suspended Derrick Shelby after the defensive lineman sat out Sunday's game following an arrest during Miami's bye week.

"We have completed our process and have made the determination to reinstate Derrick," said Dolphins coach Joe Philbin in a statement Tuesday. "Derrick understood that he would be held accountable for his actions as they did not represent our organizational standards."
