A certified letter about a personal injury claim sent to Kansas University basketball player Sherron Collins had an incomplete address on it, court documents filed Tuesday say.

The “return receipt requested” letter was not signed by Collins and, therefore, could not be delivered absent a signature, according to new motions filed by his attorney in Douglas County District Court.

The documents are the latest filings in a lawsuit filed in May by Jessica J. Brown, a former Jayhawker Towers employee who claims that in May 2007 Collins exposed himself in an elevator and rubbed against her. Last month a judge granted a default judgment to Brown because Collins had not responded to her lawsuit.

Collins has since filed motions to have the judgment set aside. Collins argues he thought an attorney who formerly represented him was handling the lawsuit.

Collins noted that at the time the personal injury claim letters were sent in March his schedule was complicated because of travel to NCAA tournament games.

Collins denies Brown’s allegations, and he has not been charged with a crime.
