Broad wicketless on return
Stuart Broad made an unremarkable return to bowling on a day where Nottinghamshire's hopes of pressuring Durham were undone by the rain.
England seamer Broad, who is playing in his first match in nearly two months as he continues to manage patella tendonitis in his right knee, bowled six overs on day two of the LV= County Championship clash, but was unable to take a wicket.
Only 25 overs were possible on Sunday, and no play after lunch, due to persistent rain at Trent Bridge, with Durham reaching 78 for two in response to Nottinghamshire's 377 all out.
Durham openers Mark Stoneman and Keaton Jennings saw off the twin threat of Broad and Australia seamer Peter Siddle, but it was forgotten man Ajmal Shahzad's double breakthrough that put the visitors under some pressure.
Shahzad, who last represented England more than three years ago, induced an edge to have Stoneman caught behind for 23, while Michael Richardson, moved up to three in place of the injured Scott Borthwick, had made just four before being bowled.
That left Durham on 47 for two, but Jennings, who was dropped twice, and Muchall (both 24 not out) took Durham to lunch, which was taken early as the rain started to fall.
The pair failed to advance their totals, however, as conditions worsened and attempts to re-start play were abandoned just after 5pm.
