New York Jets defensive Sheldon Richardson says he isn't surprised the University of Missouri football team was able to have a large impact when players staged a two-day walkout as part of protests over the school's handling of racial issues.

Richardson played for the Missouri football team from 2011-2012. He made his comments Tuesday at the Jets' team's practice facility in Florham Park, New Jersey.

Two days after the Missouri football team joined the protest, the president of the University of Missouri system, Tim Wolfe, resigned.

Richardson said, ''congrats to my boys,'' and that he was ''proud of them.''

He said that because of the money the team makes for the school, he wasn't surprised the players had an effect. He said, ''It's a numbers game.''

An assistant professor of communications at the University of Missouri is apologizing for confronting a student who was videotaping during protests on university's campus.

Melissa Click says in the statement released Tuesday that she regrets her actions a day earlier. She is seen in the video challenging student Mark Schierbecker and calling for ''muscle'' to help remove him from the protest area.

Schierbecker was filming a confrontation between a student photographer and protesters, who were preventing him from taking pictures. The confrontation drew national attention and criticism.

Click says she has apologized to Schierbecker and he accepted her apology. She also apologized to all journalists and the university community for detracting from the students' efforts to improve the racial climate on the Columbia campus.

The dean of the Missouri School of Journalism is praising a student photographer who was confronted by protesters trying to block him from recording their demonstration.

Dean David Kurpius said in a statement Tuesday the school was proud of senior Tim Tai, who was trying to take pictures Monday of protesters celebrating after hearing that President Tim Wolfe had resigned. A video of the confrontation has gotten a lot of attention online.

Kurpius said the news media have First Amendment rights to cover public events, and Tai handled himself professionally and with poise.

The statement stresses that Melissa Click, an assistant professor who called for someone to help her physically remove a videographer from the scene, has only a courtesy appointment to the School of Journalism, which was reviewing that appointment Tuesday.

About 200 people have gathered on the University of Missouri campus to hear graduate students decry the school administration's handling of racial issues on campus.

Timothy Love, a black graduate fellow in the English department, called for the school to require courses that address racial issues. He told those at the rally that students have ''a long fight ahead of us.''

Other speakers called for shared governance and urged graduate students to unionize.

The graduate student organization believes that unionization would help all minority student groups on campus and address some equity issues.

Protesters on Monday helped force the resignation of the University of Missouri System's president and the chancellor of its flagship campus, which is in Columbia.

Some University of Missouri students say protests over the killing of 18-year-old Michael Brown last year in Ferguson inspired the push for reforms at their college.

Among them is Reuben Faloughi, a third-year doctoral student, who said Monday that his experience with activism after Brown's shooting death by a police officer ''planted the seeds that students can challenge things.''

Complaints about racism had been brewing for months at the flagship University of Missouri campus in Columbia. Students took action, which led to the announcement Monday that the university system's president and the campus chancellor would resign - as well as the promise of even more changes.

Mike Sickels, another doctoral student, also credited protests in Ferguson, a St. Louis suburb about a two-hour drive from Columbia, as inspiration.
