FOXBORO -- The Patriots took the fields behind Gillette Stadium for their second day of practice against the Bears in full pads. It was a heated and highly-competitive session once again. Here's what we saw . . . 

-- The Patriots were without Rob Gronkowski for Tuesday's practice after he suffered an injury that knocked him out of Monday's workout early. Other Patriots not spotted for the session included Jabaal Sheard (third consecutive practice missed) and Shea McClellin (second consecutive practice missed).

-- Once again, Rob Ninkovich and Malcolm Mitchell were present for warmups but did not participate in practice. 

-- Danny Amendola, Dion Lewis, Sebastian Vollmer and Tre' Jackson -- all of whom are on the physically unable to perform list -- continue to be unavailable for practice. Keshawn Martin, DJ Foster, Bryce Williams and Donald Brown were once again not fully participating in practice. 

-- Safety Nate Ebner, who was added to the 90-man roster on Monday, was at practice and in a No. 43 jersey, but he was not in pads and did not participate. 

-- Julian Edelman (left), who has not participated in team work since aggravating his surgically-repaired left foot last week, took part in seven-on-seven work as well as 11-on-11 periods.

Patriots owner Robert Kraft was present for the early portion of practice. ESPN's Tedy Bruschi was also in attendance and took a few minutes to chat with Tom Brady and Julian Edelman during a punt period. 
 

-- Practice between the Bears and Patriots was chippy for the second straight day. Harold Jones-Quartey, a Bears defensive back, dropped Julian Edelman during one 11-on-11 rep. The two had been jawing at each other following 7-on-7 work and it seemed like Jones-Quartey took exception to Edelman trying to extend a play by running up the field. When he lowered his shoulder on Edelman, mulitple Patriots, including Bennett, came over to defend Edelman. Jones-Quartey was sent to the sidelines after the play by the Bears coaching staff.

-- One play later, Bennett was run over by former Patriots defensive lineman Akiem Hicks. Bennett tried to make a wham block on Hicks to clear a running lane, but he ended up taking the brunt of the collision. A few plays after that, Bennett lost his helmet and scuffled with Lamarr Houston. It was the second consecutive day that those two got into it. 

-- Bryan Stork (left) was ejected from practice when John Timu gave him an extra push after one 11-on-11 rep. Stork responded with a quick right to the area of Timu's chin strap or chest plate and followed that up with two quick shoves. Timu barely reacted and Stork was sent off. 

-- Brady (left) and Bennett worked a side session toward the end of practice in order to continue to  build their chemistry. Brady spent a good portion of their time together walking him through routes. 

-- Hicks had a good day of practice, breaking up a pass and recording a pressure on Jimmy Garoppolo in addition to his encounter with Bennett. 

-- Nate Solder appeared to suffer a left foot or ankle injury at one point that forced him to meet with trainer Jim Whalen. Solder took off his left cleat and stood on the sidelines with just one shoe for a few minutes. He eventually worked his way back in to 11-on-11 reps with the second offensive line group that included Josh Kline, Stork, Ted Karras and Cam Fleming. Waddle replaced Solder initially, then Fleming subbed in. 

-- Brady was 5-for-8 in 11-on-11 work, playing behind the second offensive line grouping. Garoppolo, meanwhile, hit on four of his nine 11-on-11 throws. Jacoby Brissett looked sharp in the work he got at the end of practice, completing seven of nine throws. 

-- Brady was particularly sharp in 7-on-7 work, completing all seven of his throws, including three to Edelman. Garoppolo completed two to Edelman, who looked very healthy as he appeares to be steadily working his way back to full participation.
