The Saskatchewan Roughriders have chosen Corey Chamblin as their new head coach and the twitterverse has gone into overdrive.

The Riders confirmed Chamblin as the new head coach in advance of a formal announcement at Mosaic Stadium at 3 p.m. CST.

On Twitter, fans and sports reporters were talking up the news and rumours well before the announcement.

The Riders have been short a head coach since the end of the season when Ken Miller stepped down.

Miller replaced Greg Marshall, who was fired following a string of losses earlier in the season.

Miller joined the Roughriders in 2007 as their offensive co-ordinator and helped the club win the Grey Cup that year, the club's first since 1989.

In two subsequent trips to the Grey Cup as head coach, Miller's Riders failed to win, however.

Chamblin was defensive co-ordinator with the Hamilton Tiger-cats in 2011.
