The Miami Dolphins avoided a major scare after an MRI showed that quarterback Ryan Tannehill suffered no structural damage in his left knee following a non-contact spill during practice. According to Aditi Kinkhabwala of the NFL Network, MRI results showed that Tannehill’s knee is as sound as it was before. As a precautionary measure, the Dolphins plan to rest Tannehill for some time during training camp.

Tannehill had a scare when he planted his left leg awkwardly as he went out of bounds after rolling to his right. The quarterback fell to the ground and remained there for about 15 seconds before walking gingerly to the locker room.

Tannehill suffered a partial ACL tear last season on that same knee, missing the last three games of the 2016 regular season. Without Tannehill, the Dolphins lost to the Pittsburgh Steelers in the wildcard game.

In the offseason, Tannehill opted for stem cell treatment instead of undergoing surgery. He was wearing a knee brace during practice on the left knee. During the offseason, the Dolphins and Tannehill both insisted that his knee was stable. "Just so everyone hears, the knee is really good. It feels really good," Tannehill said last week.

Dolphins discussed adding Kaepernick

According to Josina Anderson of ESPN, the Dolphins' front office reportedly discussed adding Colin Kaepernick as a potential insurance policy at quarterback.

The team raised the possibility as Tannehill underwent an MRI on his left knee. The Dolphins have Matt Moore as a backup while Brandon Doughty and David Fales are battling for a roster spot. The Dolphins have no third-string option as Doughty and Fales both struggled working with the third-team offense, according to Omar Kelly of the Sun-Sentinel.

With Tannehill’s knee now okay, it is unknown whether the Dolphins will pursue signing Kaepernick.

Cornerback Richard Sherman speaks his mind about Kaepernick

Seattle Seahawks cornerback Richard Sherman voiced his concern about Kaepernick still being out of work as NFL teams begin their training camps. Sherman said Kaepernick is better than quarterbacks who were signed by some teams, including that of the New York Jets.

“You’re telling me fans would rather you lose and put a worse player out there because a guy took a stand? That’s where it’s so troublesome to me,” Sherman said. The Baltimore Ravens recently expressed interest in signing Kaepernick but it was reported that the team owner has been resisting the deal. The 29-year-old Kaepernick tossed 16 touchdown passes for the San Francisco 49ers last season but he became controversial because of his kneeling during the national anthem as a sign of protest against social injustice.
