Kansas' quest for a 15th consecutive Big 12 title took another blow on Thursday night.

Senior guard Lagerald Vick takes a leave from the team, with immediate effect, the school announced.

"Lagerald has personal issues that require his immediate attention and he will take time off from our team," said coach Bill Self. "Meanwhile, we will respect Lagerald's privacy, there is no timetable for his return."

The player's mother, La Vick, told the Kansas City Star that she wanted him at home in Memphis, Tennessee.

"We need him here a few weeks," La Vick told The Star. "I need him, there's a lot going on, it's going to work out."

Vick played Tuesday in a 19-minute defeat in Kansas State's Kansas State defeat, scoring only seven points. The 6-foot-5 guard's performance has been trending downward over the season, after averaging 24.6 points and 28 points at 3 points in a five-game series. November and early December. Since scoring 29 points against Villanova on 15 December, Vick has scored only 15 points.

On the season, he averages 14.1 points and four rebounds and draws 45.5% of the distance of 3 points. In all six Kansas defeats, however, Vick's numbers dropped to 10 points on a 3-point shot from 32.4%.

Originally, Vick was not expected to Lawrence for his senior season. He declared for the NBA draft after the last season of Kansas, and Self proceeded as if Vick would not come back with the Jayhawks this season. Vick then removed his name from the draft to the great surprise of Self.

"From what we said at the end of the season, he would go somewhere else he decided to stay in school," said Self at ESPN in June. "It's something we talked about, we sort of agreed on that."

After Self traveled to Memphis to meet Vick and his mother, the school announced in late June that Vick was returning to the team.

Kansas are aiming for their 15th consecutive Big 12 title in the regular season, but the Jayhawks tied for fourth place after losing to Kansas State earlier this week. In addition to Vick, Kansas lost center Udoka Azubuike for the season due to injury in early January and no longer in second year, Silvio De Sousa, because of a problem eligibility for the NCAA. Marcus Garrett has also missed the last two games due to an ankle injury.

The Jayhawks (17-6, 6-4 Big 12) welcome the state of Oklahoma on Saturday.
