|Specsavers County Championship Division One, Emirates Old Trafford (day one):|
|Yorkshire 251-6 (96 overs): Ballance 74, Leaning 54*; McLaren 2-37, Bailey 2-82|
|Lancashire: Yet to bat|
|Yorkshire 2 pts, Lancashire 2 pts|
England seam bowler James Anderson was forced off with a tight groin on day one of Lancashire's County Championship match against Roses rivals Yorkshire.
Having reduced the Tykes to 9-2, with Anderson bowling opener Alex Lees, the 34-year-old broke down during his sixth over and had to leave the field.
Gary Ballance struck 74 as Yorkshire fought back, but his dismissal sparked a mini-collapse to leave them 178-6.
However, Jack Leaning's unbeaten 54 helped the visitors to 251-6 at stumps.
Leaning was well supported by wicketkeeper Andy Hodd (41 not out) in a partnership of 73 to at least drag Yorkshire to a more competitive score.
But the day's major talking point was the early injury to Anderson, which will be assessed again before the second day and is sure to be of concern to both his club and country.
However, the severity of the problem remains unclear and, with England's first Test match of the summer against South Africa not coming until 6 July, his international commitments may not be affected.
Despite being a bowler short, Lancashire still had the better of the opening day at Old Trafford, with Ryan McLaren (2-37) and Tom Bailey (2-82) leading the attack.
Only Ballance, whose 74 came off 163 balls and took him past 1,000 runs for the season in all competitions, and Leaning made half-centuries after Yorkshire had chosen to bat first.
