The players knew right away even if they didn’t see it.

Jaguars rookie left tackle Luke Joeckel was seriously hurt.

“I didn’t see it happen” Jaguars right guard Uche Nwaneri said. “I just heard him scream out. I knew he was in pain.”

Joeckel selected second overall in the draft sustained a broken right ankle late in the first quarter in Sunday’s 34-20 loss to the Rams at the Edward Jones Dome.

“I heard him yelling and I just walked away because I knew it wasn’t good” Jaguars receiver Cecil Shorts said. “I said a prayer for him.”

Joeckel was injured while blocking on a 1-yard run by running back Maurice Jones-Drew with 3:50 left in the first quarter. Joeckel’s leg was rolled up on by St. Louis defensive tackle Kendall Langford. He was taken off the field on a cart.

“I saw it happen it’s unfortunate” Jaguars quarterback Blaine Gabbert said. “It wasn’t pretty. My heart goes out to him because he was playing well. He was eager to be in at left tackle and was doing a great job.”

The injury came five days after the Jaguars traded left tackle Eugene Monroe to Baltimore for a fourth- and fifth-round draft pick in 2014. The Jaguars moved Joeckel to left tackle after he started the first four games at right tackle.

In three years at Texas A&M Joeckel started all 39 games at left tackle.

“He’s a young kid good player” Nwaneri said. “We all felt it when he went down. He’s a strong kid and I think he’ll bounce back. It’s tough to see that happen especially with him being back on the left side and how hard he prepared for this game.”

Without Joeckel the Jaguars played Cameron Bradfield at left tackle and Austin Pasztor at right tackle. They were rotating at right tackle prior to the injury.

Bradfield a three-year veteran has one career start at left tackle (14 starts overall). Pasztor 22 started three games at right guard last season for the Jaguars but was making his first start at right tackle.

“Cam did a nice job” Jaguars coach Gus Bradley said. “To give you an accurate assessment of his play would be unfair to him and to everybody. For him to jump in there and play both him and Austin against two really good rushers it looked like they were pretty solid.”
