With training camp marching on and week one of preseason starting to take place, injuries are an unfortunate fact of life in the NFL. Every year some teams get hit really hard by preseason injuries, losing a few key starters along the way for weeks or even the entire season.

Adjei-Barimah has fracture in his knee

Tampa Bay Buccaneers third-year cornerback Jude Adjei-Barimah has suffered a patellar fracture in his right knee. He suffered the non-contact injury during practice and it was not discovered until an MRI was taken. This is the same injury that Adjei-Barimah suffered towards the end of last season, which he has spent his offseason rehabbing from.

The 25-year-old will likely have surgery next week and could miss significant time and possibly the entire season. Last season, Adjei-Barimah played in 10 games, starting one of them. He had 22 total tackles, 2 sacks, 2 passes defended and a forced fumble as the team's nickel corner.

Kelly suffers foot injury

Indianapolis Colts starting center Ryan Kelly suffered a foot injury yesterday against the Detroit Lions during a joint scrimmage. Kelly will likely be sidelined for the rest of the preseason due to the injury but is not believed to be in any danger of missing the season opener against the Los Angeles Rams. The 24-year-old was the team's first round pick out of Alabama last season and started every game as a rookie.

McMillan tears ACL

Miami Dolphins rookie linebacker Raekwon McMillan tore his ACL in his right knee last night during the team's opening preseason victory against the Atlanta Falcons. McMillan, the team's second round pick out of Ohio State, suffered the injury while on punt coverage at the start of the first quarter.

This injury is a major blow to an already shaky Dolphins linebacking core.

McMillan has been the starting middle linebacker since training camp opened and had impressed the coaching staff. Last month the team lost presumed starter Koa Misi for the season due to a neck injury. Now, third-year linebacker Mike Hull will take over duties in the middle.

Murphy also suffers torn ACL

Washington Redskins starting outside linebacker Trent Murphy's season is over after he suffered a torn ACL and MCL in his left knee during last night's preseason defeat to the Baltimore Ravens.

Murphy was already suspended for the first four games of the season for violating the league's performance enhancing drug policy. At least he will be able to serve his suspension on injury reserve, instead of it carrying over to next season. Last season he had 46 total tackles, 9 sacks, 3 forced fumbles and 1 fumble recovery.
