Blackburn manager Steve Kean on the edge after loss to Bolton

LONDON, Dec 20 (Reuters) -- Steve Kean's tenure as Blackburn Rovers manager was left hanging by a thread after his team slumped to the bottom of the Premier League following a 2-1 home defeat by neighbours and fellow strugglers Bolton Wanderers on Tuesday.

Blackburn went behind after just five minutes when Mark Davies found space to fire home and Nigel Reo-Coker made it 2-0 for the visitors on the half-hour after more sloppy defending.

Amid chants of "Kean out" from the disgruntled home fans Blackburn responded with a Yakubu Aiyegbeni goal after 67 minutes but they could not find the equaliser and now prop up the table on 10 points from 17 matches, two behind Bolton.

In Tuesday's other game, lowly Wolverhampton Wanderers salvaged a point against promoted Norwich City in a 2-2 draw thanks to a late header from Ronald Zubar at Molineux.

The result left Norwich ninth with 21 points from 17 games, while Wolves crept up one place to 16th with 15 points, two points clear of Wigan Athletic in the relegation zone.
