The injury bug won't leave the Edmonton Eskimos alone.
After watching several key players get hurt during the first eight games of the regular season, the Esks witnessed returner Tristan Jackson injure his right ankle in practice yesterday.
The rookie speed demon went down in a heap on the field turf at Clarke Stadium on a kickoff return drill and needed the assistance of two trainers to get to the sidelines.
Putting no weight on the ankle as he hopped toward a cart, Jackson changed the atmosphere at practice in the blink of an eye.
It's unclear how serious the injury is.
"It might just be a sprain. We just need to see what it is," said Edmonton head coach Danny Maciocia.
But it also could be much worse.
Jackson wasn't available for comment after the practice mishap because the bottom of his right leg was quickly taped on the sidelines before he was taken to the dressing room via a cart.
Jackson has two returns for touchdowns in the regular season - one on a punt return and the other on a kickoff.
He also has an interception for a touchdown.
"He fell over a pile and rolled his ankle," said Maciocia, describing the play at yesterday's practice.
The Green and Gold play the host Calgary Stampeders in the Labour Day classic on Monday (2 p.m., TSN, CHED), meaning there are just two practices left before the team heads south to McMahon Stadium.
If Jackson can't play, the Esks have a few return options.
Kelly Campbell, Fred Stamps, Jason Goss or Bradley Robinson could fill his spot.
But that would mean the Esks would be using a regular position player in a double-duty scenario, which Maciocia likes to avoid.
Although Jackson has not been able to break a long return in the last month, he still has an 11.4-yard average on punt returns, which ranks fourth among regular returners in the league.
On kickoffs, his 25.8-yard average return ranks second in the league.
QUICK HITS: The Esks did receive good news on the injury front this week as defensive tackle Jim Davis has returned to practice after missing last game with an upper-body injury ... Safety Trey Young is still not practising because of an ankle injury, meaning he's doubtful.
FINISH LINES: Newly signed linebacker Derrick Doggett will be ready to play Monday if the coaching staff chooses to activate him. In his first week of practice, Doggett has impressed Maciocia.
"I think he has got a lot of energy. He runs really well," said the Esks bench boss.
Doggett could be activated to play special teams on Labour Day and be a back-up linebacker.
