The Saskatchewan Roughriders offensive line is coming off probably their best game of the year.

Now, they're in for a real big test.

the B.C. Lions come into Saturday's contest at Mosaic Stadium as the league leaders in quarterback sacks, tied with the Winnipeg Blue Bombers. The Lions are also giving up on average the least amount of yards on the ground per game. So the offensive line is probably going to have to have an even better game for the Riders to be successful.

Pretty much the reason for the Lions success on defense is their front seven, as they have arguably the best defensive line and linebacking group in the CFL.

"Even with Khalif Mitchell being out, they have some pretty good guys," said head coach Corey Chamblin.

One of those guys who is pretty good is defensive lineman Keron Williams, who comes into the game as the league's leader in quarterback sacks.

"He's just a phenomenal rusher," said Chamblin. "He plays all out every play, he has a motor and he just keeps it going."

Adding to the problems for the Riders this week is the return of linebacker Solomon Elimimian.

"They may go back to their old 3-4 defense," said Chamblin.

Last season, Elimimian was voted the hardest hitter in the CFL, but that doesn't seem to be phasing the Riders running backs.

"Is that what they say?" said Kory Sheets. "If he's playing on Saturday, I'm looking to take care of that."

Meanwhile, Jock Sanders said the key word in that sentence was last year, adding this is a new year.

All in all, it could be a very good game for fans of defensive football. The Lions may lead in most categories, but the Riders aren't too far behind.
