Earlier today Miami Dolphins starting quarterback Ryan Tannehill went down in practice with a knee injury. Now, positive news on his current status has come out. Also, the Tennessee Titans are the latest team to suffer a major wide receiver injury and the Philadelphia Eagles signed a safety.

Ryan Tannehill's current status

NFL Network reporter Aditi Kinkhabwala reported that members of the Miami Dolphins organization say that there is no structural damage to Ryan Tannehill's knee. However, his knee did buckle and right now the team will still need to make a final determination on the injury.

He will likely miss some time, although the amount of time is currently unknown.

However, the possible worst case scenario of Tannehill missing the season has passed. Backup Matt Moore will take first team reps with the offense going forward. It has been reported by ESPN's Josina Anderson that Colin Kaepernick's name has been floated around the team's front office as insurance.

Titans' first-round pick to undergo MRI

During team one-on-one drills today Tennessee Titans wide receiver Corey Davis pulled up after a catch with what is being called a hamstring injury. He did not return to practice and head coach Mike Mularkey said Davis will undergo an MRI to find out how severe the injury is. Reports out of the Titans' camp indicate that David was performing great during the first few days of training camp.

His potential loss would be a blow for the team's offense, as Davis was the key weapon added around quarterback Marcus Mariota. The receiver out of Western Michigan was selected by the team with the fifth pick in the first-round of this year's draft. In college, he set the record for being the all-time FBS leader in career receiving yards.

Eagles sign veteran Corey Graham

The Philadelphia Eagles have agreed to a one-year deal with veteran safety Corey Graham. He is familiar with defensive coordinator Jim Schwartz, who was the Buffalo Bills' defensive coordinator in 2014 when Graham was on the team. In his ten year NFL career, Graham has played for the Chicago Bears, Baltimore Ravens, and Bills.

He has played in 157 games, starting 66 of them. For his career, Graham has 603 total tackles, 60 passes defended, 15 interceptions, 3 forced fumbles, 5 fumbles recoveries, 3 sacks, and a defensive touchdown. In 2011, he made his lone Pro Bowl as a member of the Bears and helped the Ravens win Super Bowl XLVII in 2012.
