The Jacksonville Jaguars were decimated by injuries during training camp and preseason last season. This year, it was thought that if the franchise could get through the preliminary camps and preseason games without any major effects, this could be a pretty successful start to the 2013.

The thoughts were quickly squelched when Blaine Gabbert went down with an ankle injury on Monday. The severity of the injury is not known yet, but the third-year quarterback from Missouri walked off the field on his own. He received more medical attention on the sideline and in the locker room in EverBank Field.

Gabbert’s performance over the first four days in camp had been a roller coaster so far, throwing interceptions, looking erratic, fumbling snaps and looking much better in scrimmages on the third day of camp.

According to jaguars.com senior writer John Oehser, the injury did not appear to be serious.

The team does not practice on Tuesday and Gabbert will be further evaluated.

Gabbert has been in a battle since day one (actually before training camp) with backup quarterback Chad Henne for the right to start the season opener at home against Kansas City. Henne started the last six games of the season in 2012 while Gabbert was placed on injured reserve with an arm injury.

According to the jaguars.com report, when asked how he was doing in the locker room following his return from the practice, he gave a thumbs up and players were indicating he the quarterback was doing well.

What this means for the franchise and the Jaguars is unknown yet. If the injury is not severe, as it is first anticipated, then the battle continues between two quarterbacks who have not been able to separate themselves from each other so far. If it is worse than thought, then Henne then becomes the player to beat in training camp. Does it mean that Mike Kafka and rookie Adam Scott will get more reps with the first and second team? That remains to be seen.

Team head coach Gus Bradley said he saw the Gabbert injury first hand and said it looked like a lineman’s foot got knocked into Gabbert’s ankle. He also said there will be more tests to determine the severity of the injury.
