PITTSFORD, N.Y. -- Tension peaked at Buffalo Bills practice Monday, one day before the team will pack up and end training camp at St. John Fisher College.

The full-pads session ended with three intense periods of short-yardage, red zone and two-point-conversion work. After one play near the goal line, quarterback Tyrod Taylor and defensive end Shaq Lawson got in each other's faces, causing coach Sean McDermott to forcefully direct Lawson back to the sideline.

Soon after, Taylor and defensive end Jerry Hughes needed to be separated by teammates Richie Incognito and Lorenzo Alexander. Defensive coordinator Leslie Frazier called back Hughes to the sideline, where the Bills' top pass-rusher was chewed out as he vocally vented his frustrations.

McDermott met separately on the field with Hughes and defensive tackle Marcell Dareus after practice. Hughes told reporters the conversation was about an "off-field issue" unrelated to the practice. He declined to elaborate.

Here is more on Taylor's day:

Wow moment: Prior to the short-yardage and red zone work, where the focus was mostly on the running game, Taylor led the first-team offense in two move-the-ball, 11-on-11 periods. His third and final sequence was his best. Taylor led the Bills from their own 29-yard line to the defense's 25 with help from an acrobatic, 18-yard catch by Andre Holmes along the sideline. However, the offense could not advance past the 25. Taylor was sacked, had a pass intended for Anquan Boldin broken up by cornerback Leonard Johnson and then whipped a side-armed pass to running back Jonathan Williams in the flat on third-and-16 that missed its mark. It might have been a throw away from Taylor, who avoided a sack and set up a 49-yard Stephen Hauschka field goal.

Whoa moment: After Taylor's first sequence of the move-the-ball drill ended after five plays, his second sequence did not fare much better. Taylor advanced from his own 28-yard line to the 44-yard line before he and running back LeSean McCoy were not on the same page about alignment before the snap. McDermott called the offense back to the huddle. Then, on third-and-10, Taylor's pass to wide receiver Zay Jones came in a bit high and went through the rookie's hands. T.J. Yates then stepped under center to start a new series, but more alignment issues with the offense led an aggravated McDermott to call the entire team together and give a fiery speech.

"Coach brought us up and really just kind of grabbed us by the facemasks and gave us a good butt-chewing and a lot of guys needed to hear that," Incognito said. "A lot of guys at this level are not used to hearing that. The practice instantly changed. It got chippy, it got physical, it got violent. We had some live periods in there. You mix in a little bit of Coach McDermott's speech and a little bit of just being hot and tired, and you kind of get a powder keg getting ready to explode."
