Leicester consolidated their place amongst the Premiership's leaders after they ground out a 17-12 win over Gloucester at Welford Road on Saturday.
Despite the Tigers having the majority of the chances in the first half, the Cherry and Whites went into the break 6-3 ahead through two Freddie Burns' penalties to George Ford's one.
Burns added two further three-pointers in the second period, but Anthony Allen's try and the respective boots of Ford and Geordan Murphy gained Leicester a vital victory.
In a scrappy and attritional opening, the West Country outfit struggled to control proceedings with Leicester dominant in the set-piece.
And Ford opened the scoring with a penalty, but Burns quickly levelled proceedings with one of his own after seven minutes. The visitors were finding it difficult to stop the hosts' powerful scrum and another infringement in that area saw Shaun Knight sin-binned.
However, the Tigers' stand-off was awry with the boot twice in the opening period. That allowed Gloucester to gradually build a platform and Burns took Nigel Davies' team ahead.
Leicester were further hampered going into half-time when Ben Youngs was yellow carded, but the away team failed to take advantage.
Although Burns did extend Gloucester's lead when Ford became the third player to spend 10 minutes off the field, the Tigers crossed the whitewash through Allen.
Murphy, taking over the kicking duties, missed the conversion, but took the home side into an 11-9 lead with a three-pointer when Will James was sin-binned.
The respective stand-offs then traded penalties, but Ford's 70th minute effort proved decisive as the Midlands' outfit held on.
